Accelerometer TinyShield - Getting Started

by Ken BurnsFebruary 01, 2016

Overview

This TinyShield features the high performance and low power Bosch BMA250 3-axis accelerometer. The BMA250 allows measurement of accelerations in three perpendicular axes and thus senses tilt, motion, shock, and vibration in your projects. The BMA250 also has an integrated temperature sensor built in.

You can also use this TinyShield without the TinyDuino – there are 0.1″ spaced holes for power, ground, and the two I2C signals along the side of the TinyShield to allow you to connect a different system.

Technical Details

Power Requirements

Voltage: 3.0V - .5.5V

Current: 139uA (Normal Mode). Due to the low current, this board can be run using the TinyDuino coin cell option

Pins Used

A5/SCL - I2C Serial Clock line

A4/SDA - I2C Serial Data line

Getting Started Demo

This demo will set up the BMA250 accelerometer, and then loop and read the accelerometer values and print them out to the serial monitor.
